BRAIN FACTS By Yash & Lindsey

Fact Page 1  The adult human brain weighs 3 lbs.  The average human brain is 140 mm wide  The human brain has about 100,000,000 neurons  If your brain looses blood for 8-10 seconds, you will lose consciousness  Seafood makes your brain loose dementia, which is good for your brain

WHITE AND GREY MATTER  Your brain is 60% white and 40% grey matter  Grey matter is made up of neurons, which gather and transmit signals  White matter is made up of axons and dendrites which create the network by which neurons send their signals

EINSTEIN’S BRAIN His brain is similar in size to a normal human’s brain but in the region responsible for math and science, is 35% wider His brain was slightly larger than a normal brain because he exercised it more

FACT PAGE 2:  There are no pain receptors in the brain, so the brain can feel no pain  Scientists have discovered that men and women’s brains react differently to pain, which explains why they may perceive or discuss pain differently  Boredom is caused by a lack of stimulation/excitement.

Fact Page 3  Your brain is made up of 75% of water  Your brain uses 20% oxygen and 20% of the blood circulating in your body  While awake, your brain generates between 10 and 23 watts of power-or enough energy to power a light bulb  Children who learn two languages before the age of five alters the brain structure and adults have a much denser grey matter

DREAMS EXPLAINED AND COMPARED In the 1940’s and 50’s black and white dreams were very common (black and white television, etc.) Dreams could be memories or reminders, but acted out,(we don’t move unless there is a dis order that you still move in your sleep) Dreams, on average, last mins.

Fact Page 5 Lack of sleep can hurt your brain Info in your brain travels 268 mph. Humans have at least 70,000 thoughts per day London taxi drivers have a larger than normal hippocampus than most people. Especially the people that have been on the job longest. The study shows that as people memorize more info, that part keeps growing.

Fact Page 6 (last page) There are about 100,000 miles of blood vessels in the brain Those who are lefty/ambidextrous have a corpus collosum(the part that bridges the two halves) that is about 11% larger than those who are right-handed Your brain stops growing, in size, at age 18 The brain’s storage capacity is 256 exabytes(or 256 billion gigabytes). This is the equivalent to 1.2 billion average PC hard drives, enough CD’s to make a stack that can reach the moon, or 15 libraries for every person on the planet!!!

BRAAAIN GAAAMES * These tricks are made to trick your mind!!

Illusions explained ∞These illusions are all just pictures. Your brain takes a shortcut so they look like they are moving. Your brain does not take all of that time. That is called fast thinking. Fast thinking takes place when your brain tries to figure out things fast. It makes illusions look like illusions.
